Summary: Updated spamassassin packages that fix an arbitrary code execution flaw are now available. This update has been rated as having moderate security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux Desktop version 4 - i386, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64 3. Problem description: SpamAssassin provides a way to reduce unsolicited commercial email (SPAM) from incoming email. A flaw was found with the way the Spamassassin spamd daemon processes the virtual pop username passed to it. If a site is running spamd with both the - - --vpopmail and --paranoid flags, it is possible for a remote user with the ability to connect to the spamd daemon to execute arbitrary commands as the user running the spamd daemon. (CVE-2006-2447) Note: None of the IMAP or POP servers shipped with Red Hat Enterprise Linux 4 support vpopmail delivery. Running spamd with the --vpopmail and - - --paranoid flags is uncommon and not the default startup option as shipped with Red Hat Enterprise Linux 4. Spamassassin, as shipped in Red Hat Enterprise Linux 4, performs RBL lookups against visi.com to help determine if an email is spam. However, this DNS RBL has recently disappeared, resulting in mail filtering delays and timeouts. Users of SpamAssassin should upgrade to these updated packages containing version 3.0.6 and backported patches, which are not vulnerable to these issues. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. 5. Bug IDs fixed (http://bugzilla.redhat.com/): 178580 - /etc/sysconfig/spamassasin loses file context and timestamp 191033 - spamassassin looks up broken NS domain (visi.com) 193865 - CVE-2006-2447 spamassassin arbitrary command execution 6.
